Tube Positioning Using a Registration Mark

With highly automated processes in pharmaceutical industries, improper packaging can lead to disposal of thousands of products or down time.

To avoid incorrect packaging or down time, a highly accurate sensor is needed to detect the position of a tube of cream or paste, in order to ensure tubes are oriented correctly before being sealed.


  • Reduced waste and downtime.
  • Ultra fast and highly accurate for precise positioning.
  • High-quality acrylic lens suitable for food processing applications

  • Tube Positioning Using Banner's R58 Registration Mark Sensor

Banner Engineering’s R58 Expert registration mark sensor is a high-performing sensor with an ultra-fast 10 kHz switching frequency that quickly detects registration marks, which is ideal for tube positioning applications. Even with a high-gloss surface or a low-contrast situation, the R58 Expert can quickly identify the registration mark on a filled tube to determine how it should be oriented.

The R58 Expert sensor makes it easy to create optimal contrast for specific applications because it automatically selects the appropriate LED color from red, green and blue. Its outstanding color contrast sensitivity detects as low as 2% over a wide range of colors. The R58 Expert also provides simple data monitoring with an easy-to-read 8-segment bargraph display indicator for TEACH and signal strength readout and continuous readout of output status.

With a rugged zinc alloy die-cast housing and high-quality acrylic lens, the R58 Expert is suitable for heavy-duty, wash-down environments. Each sensor has two lens locations and vertical or horizontal light spot, depending on the model, for a parallel or perpendicular sensing image.
